COPD患者のドロナビノールによる息切れの軽減 (BONG)

2026年10月2日 更新者:Vejle Hospital

BONG:重度および超重度の慢性閉塞性肺疾患患者グループにおけるドロナビノールによる重度の息切れの軽減 - 無作為化、二重盲検、プラセボ対照、クロスオーバー研究

This clinical trial examines whether Dronabinol, which contains the synthetic psychoactive compound tetrahydrocannabinol (THC), can alleviate severe breathlessness in patients with severe and very severe chronic obstructive pulmonary disease (COPD).

調査の概要

詳細な説明

This study is a randomized, controlled, double-blind, crossover trial evaluating the effectiveness of the pharmaceutical drug Dronabinol in patients with severe and very severe COPD.

The researchers will compare the effects of Dronabinol with a placebo (an identical-looking substance that contains no active drug) to determine if Dronabinol reduces breathlessness in COPD patients.

After enrollment, study subjects will undergo four weeks of treatment with both Dronabinol and the placebo in a blinded and randomized sequence. There is a two-week washout period between treatments. During these treatment phases, subjects will complete questionnaires about their daily experiences of breathlessness and wear a watch that records various health parameters.

The study includes eight visits: the initial enrollment and follow-up checks every two weeks. At these visits, subjects undergo tests for lung function and walking distance, and complete health status questionnaires. Additionally, blood samples for THC levels and hair samples for cortisol analysis are collected.

介入・治療
実験的:Dronabinol 20 mg, then placebo

In this arm, the study subject will first receive dronabinol 2.5 mg capsules. For two weeks the subject will titrate dose with one capsule corresponding to 2.5 mg dronabinol every other day until 20 mg. Doses are divided into three times a day. After up titration the subject will receive 20 mg daily treatment over a period of 2 weeks. After a wash out period of 2 weeks, study subject will receive placebo capsules (matching dronabinol 2.5 mg capsules). For two weeks the subject will titrate with one capsule every other day until 20 mg. Doses are divided into three times a day. After up titration the subject will receive 8 daily placebo capsules over a period of 2 weeks.

Dronabinol 2.5 mg pr capsule. Titration up till 20 mg daily dose.
